The advent of safe and effective broad-spectrum anthelmintics has largely reduced the need to differentiate the genera and species of these parasites. In areas where Ostertagia spp predominate, the analysis of sera for increased plasma pepsinogen levels is a useful diagnostic aid. Generally, increased levels of pepsinogen activity (tyrosine. In this study, we compared the binding patterns of Cry1Ab and Cry1F toxins between both Ostrinia spp., as well as the expression of putative cadherin- and aminopeptidase-N (APN)-like protein. vae of Culex spp. and Anopheles spp., especially those breeding in polluted water. Bti and B. sphaericus have been reported to successfully control certain species of sand y (vector for the. This review of the prospects for using parasites and predators as biological control agents against Heliothis spp. includes a list of the principal parasites of the noctuids throughout the world and a list of the important predators with the principal stage attacked. Topics discussed include the distribution and abundance of Heliothis spp. in the Western and Eastern Hemispheres, increasing the.
Parasites (ectoparasites or endoparasites) are a major cause of diseases in man, his livestock and crops, leading to poor yield and great economic loss. To overcome some of the major limitations of chemical control methods such as rising resistance, environmental and health risks, and the adverse effect on non‐target organisms, biological control (biocontrol) is now at the forefront of. The pin and jab type of predatory behaviour ofRhinocoris marginatus Fabricius is distinctly different from the feeding behaviour of other subfamilies known so far. The thin long legs, tibial pads, long slender rostrum capable of more than 90° forward extension, slow gait of this predator are idenlly suited for efficient capture of soft-bodied prey types, particularly caterpillars. Heliothis armigera (Hübner) is a major pest of several crops especially tomato and pulses in India. Indigenous natural enemies likeCarcelia illota Curr.,Campoletis chlorideae Uchida,Trichogramma chilonis Ishii andHexamermis sp are unable to exert adequate control ofH. armigera in tomato. Field trials were conducted with 2 exotic parasites,Trichogramma brasiliensis (Ashmead) andEucelatoria. Manjunath TM, Bhatnagar VS, Pawar CS, Sithanantham S (). Economic importance of Heliothis spp. in India and an assessment of their natural enemies and host plants. Proc. orkshop Biol. Control of Heliothis: Increasing the Effectiveness .
The cultivated and wild food-plants of Heliothis spp., as well as their natural enemies, were studied in the cotton-growing region of the Department of Tolima, Colombia, between September and March The 4 species of Heliothis present were H. subflexa (Gn.), H. tergemina (Fldr. & Rogenh.), H. virescens (F.) and H. zea (Boddie), and they were found on 7 cultivated plant species and Seasonal occurrence of insects other than Heliothis spp. feeding on cotton in the Namoi Valley of New South Wales Article in Australian Journal of Entomology 16(2) - March with Unfortunately, this book can't be printed from the OpenBook.

Application of Elcar (Heliothis nuclear polyhedrosis virus (NPV)) to a soyabean field in Arkansas in at 9 × and 36 × polyhedral inclusion bodies (PIB) per ha resulted in only low levels of mortality (7 to %) from NPV in larvae of Heliothis spp. collected up to 14 days after treatment. Bioassay of NPV in predators collected from 36 × PIB/ha-treated plots revealed that.
